What is a SON file? A SON file is an audio file used by a Beam Software video game. It contains music, sound effects, or dialogue played within a game. SON files cannot be played by most popular media players, so if you want to play the files outside the game in which they are used, you may need to convert them to a standard audio format.

More Information Beam Software is an Australian video game developer that was founded in 1978 and acquired by Krome Studios in 2006, at which point Beam was renamed Krome Studios Melbourne. In the 1990s, Beam produced a handful of games that use their proprietary SIFF file format, including KKND2: Krossfire and The Lost Vikings II. The SIFF file format can be used to create files that contain both audio and video or just audio. When a SIFF format file contains both audio and video, it is saved with the .VB extension. When it contains just audio, it is saved using the .son extension. NOTE: Some games developed using Ubisoft LyN engine, such as The Adventures of Tintin, also use SON format audio files.
